Three conducting strips 70,72,74 respectively have touching of an arcuation and hold 71,73,75, and the sheet body other end of this first, the 3rd conducting strip 72,74 is also established the caulking groove 76,77 that an opening makes progress respectively.This three conducting strip is to be located in this spatial accommodation 42, is subjected to suitable location, and touches end with it respectively and 71,73,75 touch in the side face of this armature 50, and wherein, this second conducting strip 72 is to be positioned at spatial accommodation 42 right sides, is an outlet side conducting strip; 70,74 of this first, the 3rd conducting strips are positioned at spatial accommodation 42 left sides, generally are state arranged side by side, and its other end also corresponds respectively to this two trunking 46,47, and it is to be the input side conducting strip.The caulking groove the 76, the 77th of this two conducting strip 70,74, corresponding, just be positioned at outside these open-work 43 axial two ends.Two electric wires 78,79, electric wire 78 are the sheet bodies that are connected in the 3rd conducting strip 74 with its bare wire, and its line body is to be placed in the trunking 47, as a power input.79 in electric wire is connected in the sheet body of second conducting strip 72, and is placed in the trunking 45, as a power output end.

One diode 80 is to be located in this spatial accommodation 42, and its two end 82 also is embedded in the caulking groove 76,77 of the first, the 3rd conducting strip 70,74 respectively, makes this two conducting strip 70,74 be the conducting shape.Diode 80 root edges also are placed in this open-work 43, as shown in Figure 4.

The utility model is to establish a cover plate 90 in pedestal 40 end faces lid when using, and establishes a turning component 95 on this cover plate 90 again, can touch with the drive division 52 of this armature 50, with this armature 50 of turn.This cover plate and turning component are to be existing structure, hold and do not give unnecessary details.

Actuator state of the present utility model, please cooperate shown in Figure 3, when the primary importance shown in figure goes up, first, second bridge joint conductive part the 64, the 66th on these armature 50 side faces, the end 73,75 that touches with second, third conducting strip 72,74 touches respectively, this insulation division 54 then 71 contacts with the end that touches of first conducting strip 70, makes electric current first conducting strip 70 of can not flowing through.At this moment, power supply is from electric wire 78 input, conducts to first conductive part 64 via the 3rd conducting strip 74, multiple through bridge joint electric-conductor 60 bottom 62 and conduct to second conductive part 66, via second conducting strip 72 and electric wire 79 outputs.Then power supply and without the pressure drop of this diode 80 is flat-out output.

This turning component 95 of turn, make these armature 50 clockwise turns when next stepping position, this insulation division 54 is to contact with second conducting strip 72, this two conductive part 64,66 then touches with this first, the 3rd conducting strip 70,74 respectively, at this moment, power supply can't be exported through lead, forms off status.

When turn is to next stepping position clockwise again with this armature 50, this insulation division 54 is to touch in the 3rd conducting strip 74, this two conductive part 64,66 then touches respectively in first, second conducting strip 70,72, at this moment, the electric current and the 3rd conducting strip 74 of can't flowing through, and this first conducting strip 70 is to form a shunt current via these diode 80 pressure drops at this moment, electric current via first conducting strip 70, and the conduction of conductive part 64,66 after, be to transfer to second conducting strip 72 and export, form the output of a half-power.

Armature 50 turns are the states of replying in Fig. 3 when next stepping position, so in the state conversion in regular turn of total power output, pass and half-power output.

The utility model when using, be electric wire 78 be installed on hold wire casing 46, make it to be connected in first conducting strip 70, then during total power output, electric current is directly to transfer to second conducting strip 72 via first conducting strip 70.Under this user mode, 74 of the 3rd conducting strips form a shunt current through diode 80 pressure drops, when electric current transfers to second conducting strip 72 through the 3rd conducting strip 74, diode 80, electric-conductor 60, are half-power output.

The utility model has following effect via above structure:

One, to establish this cover plate after 90s for these pedestal 40 loam cakes, spatial accommodation 42 be form one closed empty Between, 43 formation one of this open-work are the paths of conducting with the external world, and the usefulness of heat radiation is provided, and make the switch start The time heat that produces must be distributed to the external world via open-work 43, to increase the service life.

Two, since the height of this diode 80 be for the height that is installed in all members in the pedestal, Therefore, when sinking into this open-work 43 in the diode root edge, namely get and reduce the height that diode convexedly stretches in pedestal Degree can reduce with it height of pedestal, and then reduces the volume of pedestal. Electrical equipment is with littler sky Between can accommodating this switch.

Three, the element of this switch is earlier these conducting strips to be installed in the pedestal when installing, again installing This diode. These conducting strips 70,74 caulking groove 76, the 77th, are convenient to assembler's order up Depending on the place of interlocking position, make assembler still can be easily in the small space of pedestal with diode Two shaft-like ends are aimed at the scarfing unit of conducting strips, and the interlocking that makes conducting strip and diode is quick and convenient more.

Four, because the switching device of different electrical equipments is not identical, when electric wire convexedly stretches in pedestal During diverse location, namely can affect the installing state of switch. This pedestal 40 must make input electric wire 78 look institute Need and be installed in the appearance wire casing 46 or 47, so, all must reach the result of use of switch, and also can The installation position of conversion electric wire 78 by this, makes switch be more conducive to fill in response to different electrical equipments If.
